A Viking site says there were some slender battle-axes and the photos indicate a blade about 5mm thick. Presumably most axes were about 10mm thick away from edge. Sword cuts to skulls are readily identified but do you know of any examples of skulls identified as having axe cuts? A club makes a "circular crater" so an axe-cut could be between a crater and sword-slice. Probably the surface of the bone would be rougher due to thickness of blade . Any comments much appreciated.

The National Museum of Ireland in Dublin have a couple of prime Viking-Age examples.Exhibit A is a long bone that has three square(ish) dents in its' surface from where it has been hit (but not broken) by a sword.Exhibit B is a skull with one quarter removed completely by a single axe blow.
